I have what is probably a minor problem with writing and saving to "Disk video/ram". Briefly, I edited the config file and added a line for another resolution. Works fine for almost all my saves, but there are six fractals (out of 293 processed do far) that will not save in the new mode. Can anybody tell me why?, and what I can do to fix this? Just for general info: The newly added mode is at 2560x2048. The next resolution down at 2048x1536 works on all the pictures, 'cause I've tried both. Is the problem with the cache size? Can this be adjusted? Any help, information, etc, would be greatly appreciated. Even a negative response is good, if the problem is intrinsic and I'm wasting my time trying to fix what can not be fixed. David M Fisher
